Nero burns darn slow...

Hey people...
I have something so say, see if you guys know anything about this matter....
I have around 384 MB RAM... as for now (currently with few applications running) I have around 250 MB free. But when I try to burn cds with Nero 5.5 around 12x, my computer clocks up... I can't really do anything, cause it slows down really bad. It used to happen around 16x before, so I burnt around 12x, now I can't even do that anymore and do something else in the computer. Also I have done the NERO tweak from you guys, that didn't help I think. I have a TDK 24x/10x/40x burnner, and I burn in 16x TDK CD-Rs usually...

DMA direct memory access .
In system properties/hardware/device manager/ide controller/primary controller/advanced properties/dma if available.
Also set the same in secondary ide controller if your rom or burner are on that channel.
Both your rom and burner must be dma compatable and your bios must support dma.

There could be three things causing problems with Nero and you need to do all three to get Nero working at it's best.
1. Update the ASPI layer (file is available on this site)
2. Disable the built-in burning stuff in XP, Control Panel/Administrative Tools/Services. Scroll down to IMAPI cd-burning Com Service. Right click and choose disable
3. Get the updated "wnaspi32.dll" from Ahead Software/Nero site. Install to the Nero directory.

Syedur ,
Check the above things and also check about the on the fly burning option if you get a popup that says that you have to set your CD-Rom and CD-RW drives to different IDE cables.
E.G CD-RW Primary Slave and CD-Rom Secondary Master or Slave, depends of how many HDs you've got.
